I know that this is a up and down modulation (AM) forum so pardon me for mentioning the side to side modulation format (FM), but we have on station down here in Dallas that we're using a SCA Data Systems encoder on that puts 4 seperate channels into one sub carrier. We only use it for foldback to remotes, and now that SCA Data Systems has moved on to other persuits I have no idea what will happen when the thing crashes one to many times since they will not provide us with any service data.

Now even the SCA has gone away. I have one dealer that still uses SCA in Mo.
